Climate Science

YOU WILL NOTICE in this issue some big and small changes. This is our 530th issue, which means we have been researching, writing, designing and publishing Down To Earth for 22 years. Every fortnight our aim is to bring you news, perspectives and knowledge that can help you make a difference. Our objective is to prepare you to change the world. We believe information is a powerful driver for the new tomorrow.

What we desperately shut our minds to is once again being pronounced ever more clearly: climate change is here; it is already bringing devastating extreme weather events; it will become worse in the years to come. In late September, part 1 of the fifth assessment report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) was released in Stockholm.

During my weekly conversation with my sister I told her about the unusual searing heat this June, the problems of power cuts and how we are coping in India. She, in turn, told me that in Washington DC, where she lives, there was a terrible storm that damaged her roof and uprooted trees in her garden. They were fortunate that they still had electricity, because most houses in the city were in the dark. She also said it was unbearably hot because the region was in the grip of an unprecedented heat wave.

The world can shape the debate on climate link in two ways. One, it can argue endlessly about the scientific veracity of the link between human-induced climate change and the floods in Pakistan. Two, the world can agree that even if a single event—like the Pakistan floods that drowned a fifth of the country— cannot be ascribed to climate change, there is no doubt that a link exists between such events and climate change. The Pakistan meteorological department’s data shows the country received 200 to 700 per cent more rainfall than average. Rains came in cloudbursts in ecologically fragile mountainous areas and led to natural dam bursts and floods downstream. Rains were incessant leading to more floods and greater devastation.

On a brief visit to Pakistan this week I noted that the recent floods have left deep impressions on the country’s policy and political leadership. They spoke about the scale of devastation, human suffering and the massive challenge of rehabilitation. They also noted, interestingly, that in their view there was a link to climate change.
